Honestly I don't know how this show has such high ratings. The premise is probably the best thing about it and it has many elements that attracted me to it, but the development is so poor it's almost sad. The story is engaging enough in the first episode, but after that it just drags on forever leaving this impression that nothing important is really happening. It became so boring I lost interest in many moments and even considered skipping certain parts, which is something I never do.

Oh, and don't even get me started on that stupid lighter hypnosis thingy, it was such a cheap plot device it made me feel like the drama was underestimating my intelligence.

Another thing, which just killed the drama for me, is the protagonists. I don't know who thought making the female lead behave like a 10 year old was a good idea, cause frankly it enraged me. I get that she is a mermaid so it's natural she doesn't act like a human and is more naive, but the writers literally made her a dumbass. How am I suppose to believe this womam managed to learn korean in one night by just watching dramas when she displays the IQ of a banana. Seriously, I hate the ml but I couldn't exactly blame him on not wanting to shelter her after she erased his memory and basically swam halfway across the globe for him without even thinking of a plan to get closer to him.

The male protagonist is even worse, though. He is so overbearing and possessive to the point he even becomes abusive. Like he forbids the fl of wearing certain clothes, puts a curfew on her and even stalks her. Honestly I don't know if Lee Min Ho chooses to play rich jerks or if it's just coincidence, but all his characters are horrible people.

Honestly, the story that takes place in the past with their past reincarnations or whatever is much more interesting to me, cause at least the leads there had some common sense and were more likable. It's a shame they weren't the focus of the drama, otherwise this show could've been much better.
